Table 52. CTRL7 register description
High-pass filter mode selection for acceleration data. Default value: 00
Refer to Table 53
Filtered acceleration data selection. Default value: 0
(0: internal filter bypassed; 1: data from internal filter sent to output register and FIFO)
Temperature sensor only mode. Default value: 0
If this bit is set to ‘1’, the temperature sensor is on while the magnetic sensor is off.
Magnetic data low-power mode. Default value: 0
If this bit is ‘1’, the M_ODR [2:0] is set to 3.125 Hz independently from the MODR set-
tings. Once the bit is set to ‘0’, the magnetic data rate is configured by the MODR bits
in the CTRL5 (24h) register.
Magnetic sensor mode selection. Default 10
